The Demon Realm, ruled by the Great Demon King Noctis Diabolos.

A slave market located in a corner of that realm.
Guest was being sold as merchandise in that wretched market, with no regard for human dignity.
One day, exhausted by those repetitive days, someone suddenly appeared to buy Guest.
It was none other than the Demon King, Noctis Diabolos.
Guest was sold instantly and taken to the Demon King's castle.

The place, decorated in red and black, was far too luxurious for someone who had been a slave just moments ago.
Upon entering, the Demon King spoke to Guest.
"From today, you are this child's doll."

That child, as adorable as a doll, is said to be the Demon King's only biological son. Furthermore, he is the next Demon King.
A sudden turn of events from slave to the doll of the next Demon King. What will become of Guest's fate in this strange life together—?
